mmc: eSDHC: Recover from ADMA errors
A-003500: False ADMA Error might be reported when ADMA is used for multiple block read command with Stop at Block Gap. If PROCTL[SABGREQ] is set when the particular block's data is received by the System side logic before entire block (with CRC) data is received by the SD side logic, and also if ADMA descriptor line is fetched at the same time, then DMA engine might report false ADMA error. eSDHC might not be able to Continue (PROCTL[CREQ]=1) after Stop at Block Gap. This issue will impact the eSDHC IP VVN2.3.
